MINING PLAN (changed) <br />somewhat larger than it was when the initial permit was issued to Castle Concrete, but most of the <br />land included in that initial permit is still undisturbed. The progress is detailed within the annual <br />reports. <br />Ml1Zl)Zg PZlC12 (extensive changes) <br />Introduction: The mining plan presented in this amendment includes the entire area of Table <br />Mountain that is expected to be mined. In the original permit, Phase 2 was included but not <br />planned. That land is now included in the plan. The mining of the quartzite will now be done as a <br />more or less continuous operation, but will follow a pattern that allows for compliance with lease <br />requirements and also protects adjacent resources. In particular, Area C will be operated in a <br />fashion that will limit discharge of sediment to adjacent lands and help to obscure visibility of the <br />mining from Highway 115. Setbacks, as originally established in the existing permit, will continue <br />with a minor, but important, addition to the protection of the setback zones. Some setbacks will be <br />eliminated because they will become part of the continuous mining sequence. In the existing plan <br />there was a Stage 2 portion of Phase 1. That stage has now been deleted from mining artd will be <br />used only for processing and stockpiling. <br />Most significant with this new plan is the elimination of a need to construct a new, and <br />possibly visually damaging, road to the original Phase 2 acea. Access to that area (now called <br />Area C) will now be through mined areas in Area A and Area B. This helps with maintaining the <br />integrity of the rim around the edge of Table Mountain. It restricts access to the top of the mountain <br />to only one location, the existing location. <br />Possible Lrternrittent Activity: Although it is not expected, there is a possibility that this operation <br />will be active for less than 180 days per year. If such a period were to occur, the site would be <br />secured to protect, as much as possible, against trespassers and clearly hazardous high walls and <br />other features adjusted to reduce the hazard. The site would also be inspected at least once a month <br />to insure that no environmental or safety problems are developing during the period of inactivity. If <br />the operation remains inactive for a period of 18 months, temporary seeding of areas that present a <br />potential erosion hazard would be implemented. <br />Permit/Affected Land Boundaries: In many places these two critical boundaries more or less <br />follow each other, but nowhere are they congruent. <br />Permit Boundary: The permit boundary is defined by the lease descriptions. That is, <br />because the lease description follows quarter section lines (or smaller square cornered divisions) the <br />permit boundary follows those lines. This way the permit boundary is easier to identify. <br />Affected Land Boundary: The affected land is considerably less than the permit <br />Area because it is established by the mining plan and the area expected to be disturbed. The <br />affected land is actually defined by the two types of setbacks described below. Unfortunately, the <br />affected land boundary does not form a precisely defined line except in a few locations. Along the <br />mesa edge it is defined by a minimum distance back from the edge of the mesa (50 feet), but in <br />some areas may be up to 100 feet from the edge of the mesa. <br />Table Mountain Quarry -Castle Concrete Company Exhibit D (Amendment 1) Page 2 <br />
